• Challenges identified in July 2021 GVS&DD Board Report• Constructability; solids-treatment capacity; schedule constraints; and cost increases• Compliance with regulatory deadline ~2034 (4 years late)• Estimated costs =$6.7B in 2021 dollars; $10.4B with escalation and risk reserve

• Recommending Revised Design Concept to address challenges• Committees: LWC – November 4; FIC – November 10• GVS&DD Board – November 26

• Concurrent construction of digesters and compact-footprint secondary treatment process (Membrane Bioreactor or Aerobic Granular Sludge)

• Offer capital cost savings in the order of 10%• Flexibility to validate performance and costs in preliminary design• Address commercial considerations as part of due-diligence

• What’s not changing• Tertiary level wastewater treatment • Odour control • Resource recovery opportunities• Ecological restoration projects• Iona Beach Regional Park integration

Interconnected Our work nurtures the essential connection between people and natureReconciliation-focused Relationships with Indigenous Peoples are strengthened as we journey

together along the reconciliation pathwayInclusive Equity is integral to what we do, as we create an inclusive

environment for allCollaborative By working with others, we collectively steward the land to improve

the region’s livability and ecological healthKnowledge-based Decision-making is informed by data and science, and seeks to

incorporate Indigenous ways of knowingAdaptive Through learning, innovation, and evaluation, we sustain a culture of

adaptive management
